An elongated iframe, generally designated atlj2, lf extendslongitudinallyfcf and Within the cabinet I.and comprises, see particularly Figure "l, longitudinal horizontally :spaced parallel side frame members I:3,'transverse framemernbers11".,- I5 and I6 Vspaced :along and Vvextending across between the side frame vmembers and A'secured therewithand acenter longitudinal frame member v'IFI extending kbetween .and secured with Athe The frame l2zis-detachably :mounted wit-hin the cabinet on thev short lsides .'I and vI-I thereof, in a Amanner 'here-.5 inafter described, aand when the frame is yso mounted, V.the side'zframe .members I3, the center longitudinalframefmember I'I,.and thetransverse frame member .-IA fare .disposed some distance below ,the .top for-.the .cabinet as shown in Figures rand'.

A sheet feeding mechanism, generally designatedrfat I 8 l:ami unnecessary to be -describediin detail, neeFigu-res Afland 7, Ais disposed .within the :cabinet: in'the xreg'ion of `the short Yside .I I of thercabinet `and below'the opening of the top member when the top member is in horizontal position closing 4the `cabinet top, and is mounted ure fmounted "downwardly v within Athe -ca'lbinet I adjacent the short side I I thereof, by a transmission which inclusive of a VIVbelt and pulley transmission 22, see Figure 7, also within the cabinet adjacent the short side' II thereof, and assuming the sheet feeding mechanism to be driven, sheets fed in successionl to the feed drum are fed vertically downwardly past a photographic field,l not shown, and 'are rthereafter delivered into a hopper 23, see Figures 1 and 4,

Within the cabinet I below the sheet feeding mechanism and suitably mounted on the frame A horizontal light enclosure 24, see Figure 7, is carried on the frame I2 at the level of the photographic field aforesaid, andis provided with a pair of Opposed converging reectors arranged in a horizontal plane and transversely of the vertical sheet path and obliquely to and on opposite sides of the photographic eld for reecting images of opposite faces of the fed sheets as they pass .the photographiciield toward the short side 1 of the cabinet. v

The end of the frame I2 adjacent the short side 1 of the cabinet is provided with a camera mount 26 which is inclusive of a vertical tongue 21.V A camera 28 is provided with a mount 29, see Figure 2, which is inclusive of an undercut groove 3l detachably engageable, with vertical movement of the camera, with the tongue 21 of the camera mount 25 for mounting the camera on the apparatus as shown in Figures 1 and 4.

When so mounted the camera projects from the short side 1 of the cabinet,v and this side is provided witha vertical opening 32' extending downwardly from the top of the cabinet, see Figure 7 to accommodate the camera. The top member 5 is provided with an opening 33v at the short side thereof corresponding with the short side 1 of the cabinet, see Figures 1 and 5 and this opening alines with the opening 32 .to provide for removal and installation of the camera, a hinged cover member 34 normally closing .the opening 33 and the portion of the opening 32 above the camera and being movable out of closing position for removal and installation of .,thecamera.

A camera receptable 35 is' arranged in an opening..36 in the short side 1 offthe, cabinet, see Figures 1 and 2, and being openzat its top is hinged at its lower end on the shortside 1, as designated at 31, for tilting movementffrom a closed position, shown in full lines inFigure 2, to an out- Cil wardly tilted position, shown in dot and dash lines in Figure 2, for the insertion ofthe camera into the receptacle when the copying ,apparatus is not in use and for the removalof the camera there-l from, a stop pin 38 on Hthe receptacle engaging Y Vthe inside of the short side 1 to limit outward tilting movement of the receptacle.

When the camera is mounted'on the apparatus,

as shown in Figures 1 andi,l images of both faces.V

of the fed sheets as they pass the photographic Vfield. aforesaid are reflected by the reflectors 25 to the objective, not shown, ofl the camera and are photographed on a light sensitive strip, not shown, in the camera, the sheets being illumithey pass the photographed-field. The camera is of the flow type andisfinclusive of a usual strip, feeding mechanism, not shown, for feeding the sensitized strip past the exposure aperture of the5 camera during the photographing of the sheets fed by the sheet feeding mechanism I8.

A camera drive transmissiomugenerally designated at 39 and inclusive of an electromagnetic clutch 4I., extends along and is mountedon the secure the frame I2, and the frame members areA nated by means unnecessary to bevdescribed as,

4 center longitudinal frame member I1 of the frame I2, and is driven from the sheet feeding mechanism I8 as designated at 42, so that the transmission 39 is driven from the motor 2| which drives the sheet feeding mechanism. The end of the transmission 39 which is adjacent the short side 1 of the cabinet is provided with a toothed clutch member 43. The camera 28 is provided with a toothed clutch member 44, see Figure 2, which is connected with the strip feeding means of the camera for driving the same, and when the camera is mounted on the apparatus, as shown in Figures 1 and 4, the clutch elements 43 and 44 are engaged so that the sensitized strip is fed under the control of the electromagnetic clutch 4i in synchronism with sheets fed by the sheet feeding mechanism I8 for photographing the sheets, the camera clutch member 44 being axially retractable out of engaging relation with the clutch member 43 for installation and removal of the camera. YThe electromagnetic clutch 4I is under the control of sheets fed by the sheet feeding mechanism I8 in a manner unnecessary to be described so that the sensitized strip in the camera is fed only while sheets are being photographed.

The photographic copying apparatus within the cabinet, comprising the frame I2, the sheet feeding mechanism I8, the light enclosure 24 and reflectors 25, the camera drive transmission 39 and the sheet receiving hopper 23, is removable from and installable in the cabinet I through the top opening 2 as a unit, thus facilitating assembly and servicing thereof. During such removal and installation, the belt of the belt and pulley transmission I2 is not engaged on one of the pulleys of this transmission, and to facilitate engagement and disengagement the belt with the pulley, the short side II of the cabinet is provided with an access opening 45, see Figure 4, which is normally closed by a door i6 as shown in Figure 4.

Two horizontally spaced brackets 21 are mounted on the inside of each of the short sides 1 and I I of the cabinet in downwardly spaced relation with the top of the cabinet, see Figure 7, and the ends of the side frame members I3 of the frame I2 are engaged downwardly in upright U-shaped formations 48 of the brackets. Vertical support screws 49, see Figures 9 and 10, are screwthreaded through the bottom walls of the formations 48 and engage upwardly against the ends of the frame members I3 for supporting the frame, adjustment of the screws 49 serving for leveling the frame and they being secured in adjusted position by lock nuts 5I. Set screws 52 screwthreaded through vertical walls of the formations 48 serve'to clamp the frame members I3 and shims 53 and 54 between them andthe opposite walls of the formations 48 to horizontally clamped downwardly on the support screws 29 by clamp blocks 55 clamped downwardly on ,the frame members I3 by vertical screws 56 screwthreaded downwardly into the side walls of the formations 48.

, 'A feed chute member51 is arranged 'above thel sheet feeding mechanism It and has a normal horizontal position, see Figure 1, occupying the opening 9- of the top member 5 when the top member is in its normal horizontal position closing the top of the cabinet, and the chute member is provided with a feed chute 58 through which sheets are successively fed toftliev feed drum'lSI` o f thesheet feeding mechanism ljfor the feed -termediate .transyerseirame member 4,L5 .land l:.on a diorizontal taxis .disposed itransversely auf vk.-.tlte
